Propylparaben
Ingredient Info
Propylparaben is a preservative used in skincare products to prevent bacterial and fungal growth, extending shelf life. It's one of several paraben preservatives commonly found in cosmetics and personal care products.
Benefits
- Prevents microbial contamination
- Extends product shelf life
- Cost-effective preservation
Potential concerns
- Potential endocrine-disrupting properties at high concentrations
- Detectable in human urine, suggesting systemic absorption from cosmetic use
- May reduce fecundity in animal models at very high exposures
Science: Research in Drosophila models shows propylparaben has estrogenic properties and can reduce fecundity at high concentrations (200 mM), though typical cosmetic use involves much lower levels. Human biomonitoring studies confirm paraben absorption through skincare products, but long-term health effects at cosmetic exposure levels remain understudied in humans.
